[Local treatment for persistent inflammatory arthritis of the knee: intra-articular injection of glucocorticoids and bed rest].

Two studies evaluating treatment options for persistent mono-arthritis are discussed. In one study arthroscopic lavage plus intra-articular glucocorticoids was compared with arthroscopic lavage without glucocorticoids, and with joint aspiration plus glucocorticoids. Both intra-articular glucocorticoids and lavage have their merits, but glucocorticoids appear to be slightly more effective. In the second study radioactive Yttrium plus intra-articular glucocorticoids was compared with glucocorticoids alone. Yttrium provided little additional value. There are some indications that a period of strict bed rest after treatment is beneficial. Intra-articular glucocorticoids should not be administered more frequently than three times per year in the same joint.
